Hey! Brian from Edera here. We actually forked Xen and made some improvements to it to increase performance and security. We try to upstream most of our changes but our fork is public if you want to check it out. When compared to other microvm container runtimes we can see as much as 60% performance increase for certain workloads. We've put a lot effort into making it seamlessly plug into kubernetes, happy to get you access to try it out if you're interested.
